The section holds information for dynamic linking. Currently, an object file may have only one dynamic section, but this restriction may be relaxed in the future. See `Dynamic Section' in Chapter 5 for details.

SHT_DYNSYM

0xb

SHT_FINI_ARRAY

0xf

This section contains an array of pointers to termination functions, as described in `Initialization and Termination Functions' in Chapter 5. Each pointer in the array is taken as a parameterless procedure with a void return.

SHT_HASH

0x5

The section holds a symbol hash table. Currently, an object file may have only one hash table, but this restriction may be relaxed in the future. See `Hash Table' in the Chapter 5 for details.

SHT_HIPROC

0x7fffffff

Values in this inclusive range are reserved for processor-specific semantics.

SHT_HIUSER

0xffffffff

This value specifies the upper bound of the range of indexes reserved for application programs. Section types between SHT_LOUSER and SHT_HIUSER may be used by the application, without conflicting with current or future system-defined section types.

SHT_INIT_ARRAY

0xe

This section contains an array of pointers to initialization functions, as described in `Initialization and Termination Functions' in Chapter 5. Each pointer in the array is taken as a parameterless procedure with a void return.

SHT_LOPROC

0x70000000

Values in this inclusive range are reserved for processor-specific semantics.

SHT_LOUSER

0x80000000

This value specifies the lower bound of the range of indexes reserved for application programs.

SHT_NOBITS

0x8

A section of this type occupies no space in the file but otherwise resembles SHT_PROGBITS. Although this section contains no bytes, the sh_offset member contains the conceptual file offset.

SHT_NOTE

0x7

The section holds information that marks the file in some way. See `Note Section' in Chapter 5 for details.

SHT_NULL

0x0

This value marks the section header as inactive; it does not have an associated section. Other members of the section header have undefined values.

SHT_PREINIT_ARRAY

0x10

This section contains an array of pointers to functions that are invoked before all other initialization functions, as described in `Initialization and Termination Functions' in Chapter 5. Each pointer in the array is taken as a parameterless proceure with a void return.

SHT_PROGBITS

0x1

The section holds information defined by the program, whose format and meaning are determined solely by the program.

SHT_REL

0x9

The section holds relocation entries without explicit addends, such as type Elf32_Rel for the 32-bit class of object files or type Elf64_Rel for the 64-bit class of object files. An object file may have multiple relocation sections. See "Relocation"

SHT_RELA

0x4

The section holds relocation entries with explicit addends, such as type Elf32_Rela for the 32-bit class of object files or type Elf64_Rela for the 64-bit class of object files. An object file may have multiple relocation sections. `Relocation' b

SHT_SHLIB

0xa

This section type is reserved but has unspecified semantics.

SHT_STRTAB

0x3

The section holds a string table. An object file may have multiple string table sections. See `String Table' below for details.

SHT_SYMTAB

0x2

These sections hold a symbol table. Currently, an object file may have only one section of each type, but this restriction may be relaxed in the future. Typically, SHT_SYMTAB provides symbols for link editing, though it may also be used for dynamic linking.
